The directory that should contain system headers does not exist: /usr/include

I've tried to install with this commands:
./contrib/download_prerequisites
./configure
make

and getting this error:
The directory that should contain system headers does not exist:
/usr/include
make[3]: *** [stmp-fixinc] Error 1
make[2]: *** [all-stage1-gcc] Error 2
make[1]: *** [stage1-bubble] Error 2
make: *** [all] Error 2

Now what should I do?

for modern macOS the include files are no longer stored in the file system root ( / ) so GCC cannot find them unless you tell it where they are.

If you have the Xcode command line tools installed (the easiest solution for a lot of Open Source stuff):

add --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk to the configure line

If you have only the Xcode app installed - you need to find the path inside Xcode - so add this to the configure line:

--with-sysroot=`xcrun --show-sdk-path`

This will fail even when you fix the sysroot. GCC does not support in-source builds you should make a separate build directory and

cd /path/to/build
/path/to/source/confiigure ... 
make

there is no new information in this comment to help you - perhaps you could start by recording:

  • what your installation is (version of macOS, version of xcode/command line tools)
  • what (exactly) you are using as a configuration line.
  • what the error output is.

We build the compiler many times a week on versions of macOS from 10.5 to 12. The error you first reported is caused by missing system headers (usually because the sysroot specification is missing).

macOS version 12.6, xcode-select version 2395.

configuration line: ../gcc12/configure --with-sysroot=xcrun --show-sdk-path

My directories:

~/Downloads/gcc/gcc12 - source
~/Downloads/gcc/build - build path

I deleted all, download prerequesties and install with this commands:

../gcc12/configure --with-sysroot='xcrun --show-sdk-path'
make

getting error:

ld: Assertion failed: (_file->_atomsArrayCount == computedAtomCount && "more atoms allocated than expected"), function parse, file macho_relocatable_file.cpp, line 2061.
collect2: error: ld returned 1 exit status

I think this error from my clang compiler

iains commented

this is #6

it is not a GCC problem - solutions are described here : #6 (comment)

iains commented

so I think the original reported error is resolved, and the second one reported is a duplicate (and fixed in Xcode 14.1(RC or release).
